A powerful storm has left more than 25,000 people across Ontario without electricity Monday morning.

Strong winds and heavy rain, remnants of tropical depression Ike, knocked out power in Alliston, Peterborough and Bancroft and other scattered areas across the Greater Toronto Area. In Fenelon Falls, 5,300 customers reported outages.

Power lines in some southwest regions in Ontario survived the storm unscathed, according to Hydro One.

The company says it expects service to be restored by the end of the day.

The GTA was pummelled after a weather disturbance moved across the Great Lakes area and caught on to Ike which was rapidly moving across Illinois. The combined system picked up speed and moved quickly through southern Ontario.

Nonetheless, the storm didn't pack the punch Environment Canada first predicted it would.

Wind gusts sped across the city at 50 kilometres an hour, toppling several trees. Hydro crews spent hours trying to clear the mess overnight and into Monday morning.

The national weather agency had predicted the GTA would be hit with between 30 and 60 millimetres of rain.
